WATER REGULATION SYSTEM AND METHOD OF USE THEREOF
[001] The present application claims priority from U.S. provisional
patent application
No. 62/873,547 filed on July 12, 2019.
Technical Field
[002] The present disclosure relates to water distribution in buildings,
and more
particularly water regulation systems for controlling water distribution in
buildings.
Background
[003] Water circulation systems are used to carry water into buildings
and to circulate
water throughout buildings. For example, a water circulation system may carry
water into
a house, and then circulate the water to rooms such as a kitchen, a bathroom,
or a utility
room. Water circulation systems generally provide a flow of water into a
building at all
times unless the water is manually shut off. Shutting off the flow of water
may require
manually closing a main valve of the water circulation system. Likewise,
restarting the
flow of water may require manually opening the main valve.
[004] Certain systems exist for regulating the flow of water in a building.
These
systems may include an additional valve or may be connected to a valve of the
building,
allow for the flow of water when occupants are detected on the premises of the
building.
For instance, the system may include a motion sensor that detects the presence
of an
occupant and opens the valve for a given period. However, these systems
usually have
only a single input interface allowing the user to cause the actuation of the
valve, and do
1
Date Recue/Date Received 2020-07-10
not provide for a mechanism to quickly allow an occupant to shut off the flow
of water
upon detection of a leak, or when water is not needed for a given period.
Summary
[005] The present disclosure relates to a water regulation system to be
used with the
water circulation system of the building. The water regulation system includes
a plurality
of peripheral units that communicate with a main control panel. At least a
portion of the
peripheral units includes an input interface acting as an override button,
that allows the
user to shut off the valve from any room in which a peripheral unit has been
installed. As
such, the user can rapidly use the water regulation system from his current
location to
shut off the flow of water, therefore avoiding the outpour of water as a
result of a leak.
The peripheral units communicate with the main control panel, where the main
control
panel communicates with the valve to cause the opening or closing of the
valve.
[006] In some embodiments, the water regulation system may not cause the
opening
of the valve until user input is received either at the control panel or at
one of the peripheral
units corresponding to input of the user to open the valve. Such input may
include, but is
not limited to, entering a passcode, pressing a button, providing a
fingerprint identification,
etc.
[007] A first broad aspect is a water regulation system for regulating the
water of a
water circulation system of a building or of a portion of a building. The
system includes a
water valve with an open and closed position for regulating the flow of water
into the water

of time; and
upon the input interface receiving input from a user to close the water valve,
send a
second transmission to the control panel via the connection for causing the
controller of
the control panel to actuate closing of the water valve.
[008] In some embodiments, the water valve may not reopen following the
control
panel actuating the closing of the water valve after receiving the second
transmission until
additional user input is received at the control panel or the input interface

reception of the
first transmission by the communication interface of the control panel.
[0018] In some embodiments, the control panel may cause the actuation of
the water
valve by transmitting a wireless transmission to an actuator of the water
valve that causes
the opening or closing of the water valve.
[0019] In some embodiments, the control panel may cause the actuation of
the water
valve via a wired connection to an actuator of the water valve that causes the
opening or
closing of the water valve.
[0020] Another broad aspect is a peripheral unit for use in a water
regulation system
that controls the intake of water in a water circulation system of a building
or of a portion
of the building, the water regulation system comprising a main control panel
that actuates
the opening or closing of a water valve for regulating the flow of water into
the water
circulation system of the building or the portion of the building. The
peripheral unit includes
a power source for providing power to the peripheral unit; a user input
interface; a motion

Date Recue/Date Received 2020-07-10
communication interface of the control panel; and a controller that is
configured to, upon
the motion detector detecting motion, send a first transmission to the control
panel via the
connection for causing the controller of the control panel to actuate opening
of the water
valve for a given period of time; and upon the input interface receiving input
from a user
to close the water valve, send a second transmission to the control panel via
the
connection for causing the controller of the control panel to actuate closing
of the water
valve.
[0021] In some embodiments, the user input interface may be a button.
[0022] In some embodiments, the controller may be further configured to
receive a
third transmission via the connection from the control panel to shut off the
peripheral unit.
[0023] In some embodiments, the controller may be further configured to,
when the
water valve is closed, transmit a fourth transmission via the connection to
the control
panel to cause the water valve to reopen after receiving corresponding user
input to
reopen the water valve on the user input interface.
[0024] In some embodiments, the peripheral unit may include an indicator
for signaling
to a user that the water valve is open or closed.
[0025] In some embodiments, the indicator may be a visual indicator that
illuminates
the input interface, and may display a first colour when the valve is open and
displays a
second colour when the valve is closed.
[0026] In some embodiments, the power source may be a battery, and the
peripheral

unit may include an indicator for indicating a power depletion status of the
battery.
[0027] Another broad aspect is a method of regulating water in a water
circulation
system of a building or of a portion of the building to rapidly shut off flow
into the building
or the portion of the building. The method includes detecting activity of a
user in a room
of a building; transmitting a first transmission to a control panel for
causing the opening
of a water valve, allowing water to flow into the water circulation system of
the building or
of the portion of the building for a given period; receiving user input
associated with
stopping the flow of water into the water circulation system of the building
or of the portion
of the building; and transmitting a second transmission to the control panel
for causing
the closing of the water valve, stopping the flow of water into the water
circulation system
of the building or of the portion of the building.
[0028] In some embodiments, the method may include, after the
transmitting the
second transmission, receiving user input associating with allowing the flow
of water to
return into the circulation system of the building or of the portion of the
building; detecting
further activity of a user in a room or a building; and transmitting a third
transmission to a
control panel for causing the reopening of the water valve, allowing water to
flow into the
water circulation system of the building or of the portion of the building for
a given period.
[0029] In some embodiments, the method may include after the second
transmission,
after a user provides user input at the control panel for allowing the water
valve to reopen

Detailed Description
[0047] In general, the present disclosure relates to water regulation
systems and
.. methods. These systems and methods may regulate the flow of water into a
building and
the circulation of water throughout the building. They may enable and/or
disable the flow
of water into portions of the building in response to inputs including manual
commands
and/or sensor readings.
[0048] In general, a water regulation system may enable or shut off a
flow of water
.. into a water circulation system of a building or of a portion of a building
based on a variety
of data. Data may include motion sensor activation, moisture probe readings,
and manual
override input. For example, water flow into a building may be enabled in
response to a
motion sensor, in the building being activated. For another example, water
flow into a
building may be shut off when a manual override command is given in the
building. The
following description will detail exemplary methods and the hardware and
software which
may be used to implement them.
[0049] As used herein, a building may be any type of building known in
the art. For
example, a building may be a single-family home, an apartment building,
another type of
residential building, a warehouse, a factory, an office building, or another
type of industrial
building. One skilled in the art will be able to implement the systems and
methods
Date Recue/Date Received 2020-07-10
disclosed herein in any type of building. Accordingly, systems and methods
used in any
type of building are within the scope of the present disclosure.
[0050] A building may have a water circulation system, which is
configured to allow
water to circulate throughout the building. A water circulation system may
include one or
more pipes configured to carry water into the building and one or more pipes
configured
to carry water throughout the building. A water circulation system may
optionally
additionally include elements to regulate the temperature and pressure of the
water. One
skilled in the art will be able to implement the systems and methods disclosed
herein with
any type of water circulation system. Accordingly, systems and methods used
with any
type of water circulation system are within the scope of the present
disclosure.
[0051] In a first aspect, the present disclosure relates to water
regulation systems.
Figures 1-5 illustrate water regulation systems and components thereof. The
following
description will refer to Figures 1-5. One skilled in the art will recognize
that a water
regulation system may include a combination of elements illustrated in
different Figures
and may include elements not illustrated in any Figure without departing from
the scope
of the present disclosure.
[0052] Figures 1A-1B illustrate a water regulation system 100. The water
regulation
system 100 may be configured to regulate the flow of water into the water
circulation
system of a building and the circulation of water throughout the building.
[0053] The water regulation system 100 includes a control panel 201, one or
more
11
Date Recue/Date Received 2020-07-10
water valves 102 for controlling the water entering the circulation system of
the building
or of a portion of the building, one or more peripheral units 303 and,
optionally, one or
more probes 106. In some embodiments, the water regulation system 100 may
include a
wireless communication system 104. In some embodiments, the water regulation
system
100 may also include one or more peripheral valves 105 and one or more probes
106.
Figure 1B illustrates a water regulation system 100 implemented in a building
150 with a
water circulation system 170.
[0054] The functions of the components of the water regulation system
100 will be
outlined here and described in more detail below. The peripheral units 303 may
collect a
variety of data, which may include motion sensor activations, manual override
signals,
and moisture sensor readings. The data may be communicated to the control
panel 201
via the wireless communication system 104 or a wired connection. The control
panel 201
may determine whether water flow into the building 150 should be allowed or
shut off
based on the programmable inputs or factory pre-settings. The water valve 102
may
open and close to allow/shut off a flow of water into the building 150. The
control panel
201 may communicate a signal to the building valve 102 via the wireless
communication
system 104, or via a wired connection, to open or close the building valve 102
based on
the data received from one of the peripheral units 303.
[0055] An actuator 282 may be present to open or close the valve 102,
e.g.,
pneumatically, electrically, driven by motor, etc. The actuator 282 may
receive wireless
12
Date Recue/Date Received 2020-07-10
transmission or wired transmissions from the control panel 201.
[0056] EXEMPLARY CONTROL PANEL:
[0057] Figures 2A-2C illustrate an exemplary control panel 201 in
detail, showing a
schematic diagram, a front view, and a back view, respectively. The control
panel 201
includes a main controller, an input/output interface 212, an input interface
214, a housing
215 and a power source 283.
[0058] In some embodiments, the control panel 201 may include one or
more light
and/or sound indicators 213.
[0059] The housing 215 may contain the other elements of the control
panel 201. The
housing 215 may also be configured such that it may be mounted on a wall. The
housing
215 may be accessed by a human operator, such that the human operator may
provide
input through the input interface 214 and may easily see/read the indicators
213. For
example, the housing 215 may include mounting holes 217 which allow it to be
attached
to a wall or to a support 320 (such as a support bracket). In some
embodiments, the
housing 215 may include a stand (not illustrated) or other elements which
allow it to be
disposed on a shelf or other surface. Figure 2B shows an exemplary form factor
for a
housing 215. However, the housing 215 may have any form factor without
departing from
the present teachings, provided that the housing contains the components of
the control
panel 201. In some embodiments, the housing 215 may be made of a durable,
lightweight
material, such as plastic.
13
Date Recue/Date Received 2020-07-10
[0060] As shown in Figure 1B, the control panel 201 may be mounted in an
easily
accessible location in the building 150. For example, if the building 150 is a
single-family
home, the control panel 201 may be located in a utility room. The control
panel 201 may
be located at such a position that a human operator can easily view the
indicators 213
and provide user input, for example, through the input interface 214. For
example, the
control panel 201 may be mounted on a wall at a height of about five feet.
[0061] The input/output interface 212 may be, e.g., a wireless/wired
receiver and a
transmitter, or a wireless/wired transceiver for establishing a wireless
connection with the
peripheral units 303 of the system 100. When the I/O interface 212 establishes
a wireless
connection with the one or more peripheral units 303, the wireless connection
may be a
Bluetooth connection, or any other radio frequency protocol.
[0062] The I/O interface 212 may also establish a wireless connection
with an external
computing device such as a smartphone, smartwatch, tablet, desktop computer,
laptop
computer, remote cloud etc., for receiving input and sending output wirelessly
from the
external computing device to, for instance, cause the control panel 201 to
actuate the
opening or closing of the valve, or to allow the system 100 to receive input
from the
peripheral units 303 after, e.g., input to shut off the water valve 102 has
been received at
an input interface 312 of one of the peripheral units 303, or input received
from one of the
probes 106. Other input that may be communicated to and from the control panel
201 via
the wireless connection with the computing device may include, but is not
limited to,
14
Date Recue/Date Received 2020-07-10
programmed settings of the system and/or the control panel 201, event history,
etc.
[0063] In some examples, where the control panel 201 sends the commands
to
actuate the water valve 102, the I/O interface 212 may also communicate with
the actuator
of the water valve 102.
[0064] In other examples, the control panel 201 may have a wired connection
with the
actuator 282 of the water valve 102 to transmit via the wired connection the
commands
to actuate the water valve 102.
[0065] The controller of the control panel 201 may include a processor
211 and
memory 281 as is known in the art. The processor 211 may be connected to the
memory
281 via a BUS. The memory 281 stores instructions in the form of program code
that,
when executed by the processor 211, causes the control panel 201 to transmit
commands
to actuate the control valve 102.
[0066] For instance, the program code stored in memory 281 may be
adapted to cause
the control panel 201, when executed by the processor 211, to send out a
command to
actuate the opening of the water valve 102 when the I/O interface 212 of the
control panel
201 receives a wireless transmission from a peripheral unit 303 after the
peripheral unit
303 detects activity in a room, using, for instance, a motion detector. After
the passing of
a period of time calculated using, e.g., a timer of the control panel 201, the
processor 211,
upon execution of program code stored in memory 281, may send out instructions
to
actuate the closing of the water valve 102 until, e.g., further input is
received from a
Date Recue/Date Received 2020-07-10
peripheral unit 303 that user activity has been further detected in the
building 150.
[0067] The program code stored in memory 281 may be adapted to cause the
control
panel 201 to, when executed by the processor 211, send out a command to
actuate the
closing of the water valve 102 when the I/O interface 212 of the control panel
201 receives
a wireless transmission from a peripheral unit 303 after the peripheral unit
303 receives
user input to close the water valve 102 (e.g. pressing of a manual override
button). The
control panel 201 may then not allow for reopening of the water valve 102
until input to
this effect has been received at the control panel 201 or at one of the
peripheral units
303.
[0068] The user input interface 214 may include a button or keypad that
provides for
a manual override function to cause the shutting of the water valve 102. When
the user
input received at the user input interface 214 corresponds to the shutting of
the water
valve 102, the main controller may process this instruction and produce a
command to
shut off the flow of water to the building 150. The command may be transmitted
to the
building valve 102.
[0069] In some embodiments, the user input interface 214 may include an
indicator
that indicates to the user if the valve is open or closed. For instance, the
indicator may be
a light that flashes and/or changes colour, e.g. goes from green to red, when
the valve
goes from an open position to a closed position. In other embodiments, the
indicator may
be a source of sound (e.g. a speaker) that projects a beeping noise once the
valve is in
16
Date Recue/Date Received 2020-07-10
a closed/open position. It will be understood that other indicators for
indicating to a user
if a valve is opened or closed may be provided without departing from the
present
teachings.
[0070] In some embodiments, the input interface 214 may receive input
for providing
two settings, when the input is received and processed by the controller of
the control
panel 201, generating the corresponding transmission to actuate the water
valve 102.
The first setting could be tied with shutting off the water for a given
period, where the
second setting could be tied with shutting off the water until further input
is provided to
turn on the valve. For instance, the first input may be a quick press of the
button of the
input interface 214, where the second input may be holding the button of the
input
interface 214 for a longer period.
[0071] In some embodiments, the controller of the control panel 201 may
be adapted
to not reopen the water valve 102 following a manual override to shut off the
water until
user input is further received at, e.g., the user input interface 214 (or 314
at the peripheral
unit 303) to allow a flow of water into the building 150. For instance, when
the input
interface 214 includes a keypad, the entering of a passcode may cause the
control panel
201 to reopen the water valve 102 if a transmission is received from a
peripheral unit
corresponding to the detection of activity in the building 150. In other
embodiments, the
user input received at the input interface 214 or 314 (indirectly) causes the
transmission
of a command to reopen the valve without there needing to be any further
activity detected
17
Date Recue/Date Received 2020-07-10
by one of the peripheral units 303. The input may be the pressing of a button,
to cause
the reopening of the valve.
[0072] The control panel 201 may optionally include a motion detector
216. The
motion detector 216 may detect motion in front of the control panel 201 and
transmit
motion detection information directly to the main controller. The main
controller may
process this information and produce a command to enable the flow of water
into the
building 150. In some embodiments, it may be desired that the motion detector
216 detect
persons entering or leaving a room/area in which the control panel 201 is
located. For
example, Figure 1B shows a control panel 201 located in a utility room. The
control panel
201 may be mounted near a door of the utility room to detect persons
entering/leaving
the utility room.
[0073] The control panel 201 includes a power source 283. For example,
the power
source 283 may be an outlet connection or a battery connection. It will be
appreciated
that other power sources 283 may be used without departing from the present
teachings.
[0074] The building valve 102 is illustrated in Figures 1A-1B. The building
valve 102
of the water regulation system 100 may allow or stop the flow of water into
the building
150. The building valve 102 may be any type of valve known in the art, such as
a gate
valve or a ball valve. The building valve 102 may be configured to simply
allow or disallow
the flow of water into the building 150 or may also be configured to control a
rate of flow
of water into the building 150. As shown in Figure 1B, the building valve 102
may be
18
Date Recue/Date Received 2020-07-10
disposed within a main pipe 171 of the water circulation system 170.
[0075] In some embodiments, the control panel 201 may have a probe
interface 284
(such as a port) for establishing a connection (e.g. a wired connection) with
a probe 106,
as further described herein.
[0076] As discussed above, the building valve 102 may be controlled by the
main
controller of the control panel 201. To this end, the building valve 102 may
include a
communication module (not illustrated). The communication module may be
connected
and may both receive and transmit data via a wireless or wired connection from
the control
panel 201. For example, the communication module may receive commands to open
or
close the building valve 102 and may transmit information about whether the
building
valve 102 is open or closed. The communication module may comprise a
transmitter and
a receiver or any type of hardware known in the art which is capable of
receiving and
transmitting data. The actuator may process data received by the communication
module. The actuator 282 opens or closes water valve 102 as a function of the
commands
received from the control panel 201.
[0077] The control panel 201 may also include one or more visual
indicators 213. The
visual indicators 213 may be a series of lights (e.g. LEDs) or pairs of LEDs
that light up
or provide light of a particular wavelength upon said control panel 201
receiving a
transmission from a peripheral unit 303 that activity has been detected by the
peripheral
unit 303. As such, each of the peripheral units 303 may be associate with one
of the visual
19
Date Recue/Date Received 2020-07-10
indicators 213 of the series of visual indicators 213.
[0078] For instance, when motion is detected by the peripheral unit 303
found in the
bathroom, and a transmission is received from the peripheral unit 303 of the
bathroom,
with, e.g., an identifier code or data indicative of the source of the
transmission, the
controller of the control panel 201 may process the data and light up the
visual indicator
213 corresponding to the peripheral unit 303 located in the bathroom (e.g.,
represented
by light indicator 213 "2"). As such, when the system 100 is installed, the
control panel
201 may be configured to associate each of the peripheral units 303 with a
given number,
such that a user can monitor whether occupants are present in different
portions of the
house 150 using the visual indicators 213.
[0079] In some embodiments, the control panel 201 may be integrated to
the alarm
system of a building or may be a keypad module for an alarm system. The
control panel
201, also acting as an alarm system, may provide a message wirelessly to the
computing
device (e.g. smartphone) of the user when a leak has been detected, when the
valve has
been shut off due to a manual override, etc. As such, the control panel 201
may include
the features of an alarm system as is known in the art, such as an established
connection
with an alarm monitoring service that warns the user when an event has been
detected
by the system. In the present example, such an event may include the detection
of a leak,
when a user has shut off the valve using a manual override button, etc.
[0080] EXEMPLARY PERIPHERAL UNIT WITH MOTION SENSOR:
Date Recue/Date Received 2020-07-10
[0081] The control panel 201 is in communication with one or more
peripheral units
303 located throughout the building. The peripheral units 303 may be provided
with
different components depending on their utility and the information they
collect for the
water regulation system 100, as shown in Figure 3A.
[0082] Figures 3A, 3B and 3D illustrate exemplary peripheral units 303 with
a motion
sensor, showing a schematic diagram and an isometric view, respectively. A
water
regulation system 100 may include any number of peripheral units 303.
[0083] The peripheral unit 303 includes a controller, an input/output
interface 312, a
user input interface 314 and a housing 319. The peripheral unit 303 may
include a probe
interface 384 for connecting the peripheral unit 303 to a probe 106. The probe
interface
384 may be a port (a female end) for receiving the male end of a connector.
[0084] When the probe 106 detects the presence of water, a signal can be
sent via
the connector between the peripheral unit 303 and the probe 106 to the
peripheral unit
303. The peripheral unit 303, receiving the signal of the presence of water,
may send a
command to the control panel 201 for causing the control panel 201 to actuate
the closing
of the water valve.
[0085] As shown in Figure 1B, peripheral units 303 may be located
throughout the
building 150, especially in areas/rooms with running water. For example, if
the building
150 is a single-family home, peripheral units 303 may be mounted in the
kitchen and the
bathrooms.
21
Date Recue/Date Received 2020-07-10
[0086] The peripheral units 303 may be installed at eye level, such that
a user may
easily access the input interface 314 (e.g. button) located on each of the
peripheral units
303, and also such that the activity sensor 316 of the peripheral unit 303
detects the
presence of an occupant in the room.
[0087] The housing 319 may contain the other elements of the peripheral
unit 303.
The housing 319 may also be configured such that it may be mounted on a wall
where it
may be accessed by a human operator, such that the human operator may provide
input
through the manual override 314. For example, the housing 319 may attach to an
optional
mounting plate 320 which may allow it to be attached to a wall. For example,
peripheral
.. units 303 may be mounted on walls of the building 150 in easily accessible
locations, at
a height of about five feet. In some embodiments, the housing 319 may include
a stand
(not illustrated) or other elements which allow it to be disposed on a shelf
or other surface.
Figure 3B shows an exemplary form factor fora housing 319. However, the
housing 319
may have any form factor known in the art. In some embodiments, the housing
319 may
.. be made of a durable, lightweight material, such as plastic.
[0088] The I/O interface 312 may both receive and transmit data.
Specifically, the I/O
interface 312 may receive data from and transmit data to the control panel
201. The I/O
interface 312 may comprise a transmitter and a receiver or any type of
hardware known
in the art which is capable of receiving and transmitting data. The connection
established
between the I/O interface 312 and the I/O interface 212 may be wired or
wireless.
22
Date Recue/Date Received 2020-07-10
[0089] The peripheral controller includes a processor 318 and memory
381. The
processor 318 may be connected to the memory 381 via a BUS. The memory 381
stores
instructions in the form of program code that, when executed by the processor
318,
causes the processor 318 to perform certain tasks.
[0090] The peripheral unit 303 may process data received by the I/O
interface 312 and
produce data/commands to be transmitted by the I/O interface 312. Processing
the data
may comprise preparing the data to be sent to the control panel 201. For
example, the
peripheral unit 303 may package received data about a moisture level in a
format
readable by the processor 211 of the control panel 201. The data may be
transmitted to
the control panel 201 via the wireless communication system 104. ((The
processor 211
may then determine whether the building valve 102 should remain open until a
programmed auto shut off is activated or closed based on unacceptable moisture
data.))
The peripheral unit 303 may include logic components that perform the
processing
described above and memory components that store code for operations logs of
the
peripheral unit and/or received or produced data. These components may be any
type
of logic and memory known in the art.
[0091] The motion detector 316 may detect motion in front of the
peripheral unit 303
and transmit motion detection information directly to the processor 318. The
processor
318 may process information and produce data to communicate to the control
panel 201.
The data may be transmitted to the control panel 201 via the wireless
communication
23
Date Recue/Date Received 2020-07-10
system 104 or hard wire. The motion detector 316 may be any type of motion
detector
known in the art, such as an ultrasonic sensor, an infrared sensor, a
microwave sensor,
or a tomographic sensor.
[0092] In some embodiments, it may be desired that the motion detector
316 detect
persons entering or leaving a room/area in which the peripheral unit 303 is
located. For
example, Figure 1B shows a peripheral unit 303 located in a bathroom. The
peripheral
unit 303 may be mounted near a door of the bathroom to detect persons
entering/leaving
the bathroom. In such embodiments, information about the detected motion may
be
transmitted to the control panel 201, which may in turn, produce a command to
open a
flow of water into the building 150.
[0093] In some embodiments, the main controller of the control panel 201
can
determine a length of time since motion was last detected by any of the motion
detectors
216, 316. If this length of time exceeds a programmed threshold time, the
processor 211
may produce a command to shut off the flow of water into the building 150. The
command
may be transmitted to the building valve 102 via the I/O interface 212.
[0094] The user input interface 314 may allow a human operator to
provide a
command directly to the peripheral controller and may comprise a button or
keypad. In
some embodiments, the user input interface 314 may be a manual override e.g.,
button
or switch. The manual override may allow a human operator to provide an
instruction
directly to the peripheral controller to communicate a command to the control
panel 201
24
Date Recue/Date Received 2020-07-10
to shut off a flow of water into the building 150. The controller of the
control panel 201
may process this instruction and produce a command to shut off the flow of
water to the
building 150. The command may be transmitted to the building valve 102. In
some
embodiments, the same manual override or an additional manual override/user
input may
also allow an operator to provide a command to allow a flow of water into the
building
150.
[0095] In some embodiments, the user input interface 314 may include an
indicator
that indicates to the user if the valve is open or closed. For instance, the
indicator may be
a light that flashes and/or changes colour, e.g. goes from green to red, when
the valve
goes from an open position to a closed position. In other embodiments, the
indicator may
be a source of sound (e.g. a speaker) that projects a beeping noise once the
valve is in
a closed position. It will be understood that other indicators for indicating
to a user if a
valve is opened or closed may be provided without departing from the present
teachings.
The indicator of the user input interface 314 may also indicate the valve
status (e.g. open
/ closed) when the motion detector 316 picks up the presence of a user (e.g.
motion
detection signal sent by the motion detector 316 the processor, the processor
causing the
indicator of the user input interface 314 to present an indication).
[0096] The manual override found on each of the peripheral units 303 may
provide
several important advantages for the water regulation system 100. The manual
override
may enable human operators to quickly shut off the flow of water into a
building 150 by
Date Recue/Date Received 2020-07-10
providing a simple input, for example by pressing a button. Further, the
peripheral units
303 may be located in rooms/areas where running water is present, such as
bathrooms
and kitchens. Accordingly, the manual override 314 can be activated as soon as
a leak
or other problem occurs. This may enable the water regulation system 100 to
respond
rapidly to problems with the water circulation system 170, thereby increasing
the safety
of the building 150.
[0097] In some embodiments, the input interface 314 may receive input
for providing
two settings, when the input is received and processed by the controller of
the peripheral
unit 303, generating the corresponding transmission to the control panel 201
as a result.
The first setting could be tied with shutting off the water for a given
period, where the
second setting could be tied with shutting off the water until further input
is provided to
turn on the valve. For instance, the first input may be a quick or short press
of the button
of the input interface 314, where the second input may be holding the button
of the input
interface 314 for a given period.
[0098] The peripheral units 303 may be powered through any means known in
the art.
For example, the peripheral unit 303 may include a power source 383. The power
source
383 may be, for instance, a battery or a connection to a power outlet through,
e.g. an
AC/DC converter. The power source 383 may also be connected to the control
panel 201,
the peripheral unit 303 receiving power from the control panel 201 (powered
via power
source 283).

A peripheral unit 303 may include an indicator 322 which shows the battery
charge level.
[00100] In some examples, as shown in Figure 3D, the housing 319 of the
peripheral
unit 303 may be shaped such that it may fit in a socket box or a light switch
box. In some
examples, the peripheral unit 303, via the controller, may also control the
opening or
closing of lights in a room, via an input interface (e.g. a button, toggle
switch, etc. not
illustrated), or via the motion sensor 316, where the lights turn on for a
given time upon
the detection of motion in a room.
[00101] EXEMPLARY PERIPHERAL UNIT WITH HUMIDITY SENSOR:
[00102] Reference is now made to Figure 3C, illustrating an exemplary
peripheral unit
303 with a humidity sensor 321. The peripheral unit 303, also referring to
Figure 3A, can
be, for instance, placed under a water-consuming appliance (e.g. a washing
machine,
fridge, dish washer) or close to a source of water (e.g. a sink), where the
humidity sensor
321 detects the presence of moisture (e.g. water). The controller, upon
receiving a signal
from the humidity sensor 321 that moisture has been detected, transmits a
command
(e.g. wirelessly) to the control panel 201 to causing the shutting off of the
water valve.
[00103] In some embodiments, the peripheral unit 303 of Figure 3C may also
include a
probe interface 284 for connecting to a probe 106, where the probe 106 can be
placed
under another water-consuming apparatus or source of water.
[00104] As such, the peripheral unit 303, connected to the probe 106, can
detect the
27
Date Recue/Date Received 2020-07-10
presence of moisture under either of the water-consuming apparatuses and/or
sources
of water.
[00105] As shown in Figure 3C, the humidity sensor 321 may be a set of metal,
conductive tabs that form a circuit when water is present (the tabs connected
by the
presence of water).
[00106] The controller of the peripheral unit 303 may also process data
collected by the
humidity sensor 321 and produce data/commands to be transmitted by the I/O
interface
312. For example, the controller may process data collected by the humidity
sensor 321
or another sensor, 106 for instance. Processing the data may comprise
preparing the
data to be sent to the control panel 201. For example, the controller may
package
collected data about a moisture level in a format readable by the I/O
interface 212 of the
control panel 201. The data may be transmitted to the control panel 201 via
the wired or
wireless connection established between the peripheral unit 303 and the
control panel
201. The probe controller may include logic components that perform the
processing
described above and memory components that store code for running operations
of the
probe controller and/or received or produced data. These components may be any
type
of logic and memory known in the art.
[00107] In some examples, the base of the peripheral unit 303 may be flat such
that the
peripheral unit 303 may be placed, e.g., flat or standing on the floor next
to. e.g., an
appliance. The humidity sensor 321 may be located on the flat base of the
peripheral unit
28
Date Recue/Date Received 2020-07-10
303. As such, when water seeps onto the floor, as a result of, e.g., a leak
from a fridge,
the humidity sensor 321 may detect the presence of water, the controller of
the peripheral
unit 303 sending a transmission to the control panel 201 for causing the
closing of the
water valve 102.
[00108] The peripheral unit 303 with the humidity sensor 321 may also have an
input
interface 314 for, e.g., sending an override command to the control panel 201
to shut off
the valve 102.
[00109] With reference to Figure 3E, in some embodiments, the peripheral unit
303 with
humidity sensor 321 may include a mounting for fastening to a surface, e.g. a
vertical
surface of, e.g., a sink, a bath, etc. As such, as the water in the sink or
bath rises, the
moisture sensor 321 detects the presence of water, and the controller,
following the
detection of moisture or water, transmits a wireless transmission to the
control panel 201
of the peripheral unit 303 for causing the closing of the water valve 102.
Exemplary
fasteners include, but are not limited to, a suction cup, an adhesive, a
magnet, a string
attached at one end to the back of the housing 319 and at the other end to a
hook for
hooking onto the edge of the sink or bath, etc.
[00110] As shown in Figure 3E, the peripheral unit 303 may also include a
bracket 343
with side walls with grooves for receiving the rest of the peripheral unit 303
and for holding
the rest of the peripheral unit 303 in a snug fit. The back of the bracket 343
may include
the fastener for fastening to a surface, such as a vertical surface. Exemplary
fasteners
29
Date Recue/Date Received 2020-07-10
include, but are not limited to, a suction cup, an adhesive, a magnet, a
string attached at
one end to the back of the housing 343, etc.
[00111] As such, the peripheral unit 303 of Figure 4B may be disposed in an
area in
which the presence of moisture is of interest. For example, if the peripheral
unit 303 is
part of a water regulation system 100 in a single-family home, the peripheral
unit 303 may
be disposed in a sink or a bathtub, such that the moisture sensor 321 may be
submerged
if the water in the sink or the bathtub rises above a certain level. A
peripheral unit 303
may also be disposed outside of a sink, bathtub, washing machine, or other
appliance
which may be filled with water and where space is restricted. In such a
configuration, the
moisture sensor 321 may become wet if the appliance overflows.
[00112] EXEMPLARY PROBE:
[00113] Reference is now made to Figure 4, illustrating an exemplary probe 106
for
connecting to a peripheral unit 303, or a control panel 201 of the water
regulation system
100.
[00114] The probe includes wiring 123 ending with a connector (e.g. a male
connector)
for connecting to a probe interface 284 (e.g. port) of the control panel 201
or the probe
interface 384 of a peripheral unit 303.
[00115] The probe 106 does not have to be powered, instead, it may include a
humidity
sensor 112 for detecting the presence of moisture (e.g. water). The humidity
sensor 112
may be a set of tabs made from a conductive material that form a circuit when
water is
Date Recue/Date Received 2020-07-10
present, sending a signal to the peripheral unit 303 or control panel 201 when
moisture
is detected via the wiring 123.
[00116] The housing 119 of the probe 106 may be thin, such that the probe 106
can be
slid under a water-consuming apparatus, or a water source (e.g. a sink).
[00117] COMMUNICATION BETWEEN MODULES OF THE WATER REGULATION
SYSTEM:
[00118] In some examples, when the communication between the modules is
wireless,
the wireless communication established between the components of the system
100 may
be a short-range wireless communication, such as Bluetooth. In other examples,
the
communication may be by radio frequency. In other examples, the communication
may
be over WiFi or a local area network.
[00119] One skilled in the art will recognize that a water regulation system
100 could
be implemented using wired connections instead of or in conjunction with the
wireless
communication system 104. Further, one skilled in the art will readily
understand how to
implement wired connections between the components of the water regulation
system
100 described above. Such a modification falls within the scope of the present
disclosure.
[00120] ADDITIONAL PERIPHERAL VALVES:
[00121] As discussed above, a water regulation system 100 may optionally
include one
or more peripheral valves 105. Figure 1B illustrates three peripheral valves
105. Each
peripheral valve 105 may control the flow of water to a particular region of
the building
31
Date Recue/Date Received 2020-07-10
150 (e.g. a unit of a condominium, a floor of a building, an office space,
etc.) Accordingly,
each peripheral valve 105 may be disposed in a secondary pipe 172 of the water
circulation system 170 that carries water to a particular region. For example,
as shown
in Figure 1B, the building 150 may be a single-family home, and the water
circulation
system 170 may include two secondary pipes 172 which carry water to a bathroom
and
a utility room. Each of the peripheral valves 105 may be disposed in one of
the secondary
pipes 172, such that opening/closing each peripheral valve 105 may allow/shut
off the
flow of water into the bathroom, or the utility room. The peripheral valves
105 may be
any type of valve known in the art, such as a gate valve or a ball valve. The
peripheral
valves 105 may be configured to simply allow or disallow the flow of water
into the building
150 or may also be configured to control a rate of flow of water into the
building 150.
[00122] EXEMPLARY METHOD FOR REGULATING WATER IN A BUILDING:
[00123] In a second aspect, the present disclosure relates to methods for
water
regulation. The methods described below may use the water regulation systems
described above or any other type of hardware and software known in the art.
Methods
according to the present disclosure include methods of turning on a flow of
water into a
building and methods of shutting off a flow of water into a building. Figures
Sand 6 outline
such methods.
[00124] Figure 5 outlines a method 500 of controlling a flow of water into a
building
based on user input. The following description refers to Figures 1-5 to
describe the
32
Date Recue/Date Received 2020-07-10
method in detail and to demonstrate how a water regulation system may be used
to
implement it. The method outlined in Figure 5 may be performed by a water
regulation
system 100 including a peripheral unit 303, a communication module 104, a
control panel
201, and a building valve 102. However, it will be understood that any other
water
regulation system in accordance with the present teachings may be used to
perform the
method 500.
[00125] In step 541, a peripheral unit 303 may detect the presence of a human
operator.
The detection may be performed by a motion detector 316 as described above.
[00126] In step 542, the peripheral unit 303 may receive user input. The human
operator may provide user input through a user input interface 314, which may
comprise
a button, keypad, voice recognition system, or other combination of hardware
and
software. In some embodiments, the user input interface 314 may be a manual
override
and the peripheral unit 303 may receive a manual override instruction from the
human
operator. This user input may be performed when, for instance, the user
detects a leak
and would like to rapidly close water entering the building. In other
examples, the user
may be exiting the building for a prolonged period, and as such would like to
prevent
water circulating in the building during its absence.
[00127] Following step 541 or step 542, at step 543, the peripheral unit 303
may
transmit a transmission to the control panel 201 for causing the
opening/closing of the
water valve 102. The transmission may be sent via a I/O interface 312 of the
peripheral
33
Date Recue/Date Received 2020-07-10
unit 303 over the wireless connection established with the I/O interface 212
of the control
panel 201. In some embodiments, the transmission may be performed over a
Bluetooth
connection, or via one or more radio frequency signals. In some embodiments,
the
peripheral unit 303 may process/package the user input before transmitting it
to the
control panel 201.
[00128] In some examples, where the system 100 includes a peripheral unit 303
with a
humidity sensor 321, detection of moisture by the humidity sensor 321 may
cause the
peripheral unit 303 to send a transmission to the control panel 201 for
causing the closing
of the valve 102. The detection of moisture could be a sign of a leak or,
e.g., the
overflowing of a bathtub or of a sink.
[00129] In step 544, the control panel 201 may receive the input from the
peripheral
unit 303. In some embodiments, the I/O interface 212 may receive the input and
transfer
the input to a main controller of the control panel 201.
[00130] In step 545, the control panel 201 may process the received input and
produce
a valve command for shutting the valve 102. The main controller 211 may
analyze the
input and determine whether the flow of water to the building should be
allowed or shut
off. If the flow of water should be allowed, the main controller 211 may
produce a
command to open the building valve 102. If the flow of water should be
shutoff, the main
controller 211 may produce a command to close the building valve 102. In the
present
example where the received transmission is a manual override instruction, the
main
34
Date Recue/Date Received 2020-07-10
controller 211 may determine that the manual override instruction indicates
that the flow
of water should be shut off and produce a valve command to actuate the closing
of the
building valve 102.
[00131] In step 546, the control panel 201 may transmit the valve command to
the
building valve 102. The transmission may be performed by a I/O interface 212
of the
control panel 201 wirelessly. In some embodiments, the transmission may be
performed
over a wired connection.
[00132] In step 547, the building valve 102 may receive the valve command from
the
control panel 201. In some embodiments, a I/O interface (not illustrated) of
the building
valve 102 may receive the input and transfer it to a valve controller (not
illustrated). As
discussed above, the valve command may be a command to either open the
building
valve 102 or close the building valve 102.
[00133] In step 548, the building valve 102 may either open or close in
response to the
valve command. In an exemplary embodiment, the valve command may be a command
.. to close the building valve 102 produced in response to a manual override
instruction. In
such an embodiment, the building valve 102 will close, stopping the flow of
water into the
building.
[00134] It should be recognized that steps 542-548 can be performed rapidly by
a water
regulation system 100. Accordingly, the flow of water into a building can be
rapidly
stopped or started by a user using the water regulation system 100. This may
prevent
Date Recue/Date Received 2020-07-10
water leaks from becoming dangerous or damaging by stopping them quickly. The
steps
may also be performed with minimal input from a human operator. For example, a
human
operator may only be required to press a manual override button or otherwise
provide
user input. Further, the human operator may be able to provide this input from
the site of
a water leak, without having to physically interact with the building valve,
which may be
at a different location.
[00135] Methods of controlling a flow of water into a building based on user
input may
include variations on the steps shown in Figure 5 and may include additional
steps not
shown therein. One skilled in the art will readily understand how to implement
these
based on the description of the water regulation system 100 provided above.
[00136] In some embodiments, the user input may be provided to the control
panel 201
instead of to a peripheral unit 303. As described above, the control panel 201
may include
a manual override or other user input interface and is accordingly capable of
receiving
user input. In such embodiments, the user input would not be transmitted from
the
peripheral unit 303 to the control panel 201, but rather would originate at
the control panel
201. The user input may be processed and the building valve 102 may be
commanded
in the same manner as described above.
[00137] In some embodiments, the method may open/close a peripheral valve 105
instead of or in addition to opening/closing the building valve 102. In step
545, the main
controller 211 may determine which valve(s) 105, 102 should be commanded; in
step
36
Date Recue/Date Received 2020-07-10
546, the command may be transmitted to the selected valve(s) 105, 102. Steps
547-548
may be carried out by the building valve 102 and/or the peripheral valves 105.
[00138] In some embodiments, the water regulation system 100 may display a
status
of the building valve 102 and/or peripheral valves 105 to a human operator.
The display
may comprise an indicator or other visual display on the peripheral units 303
and/or on
the control panel 201. The status of the building valve 102 may be
communicated from
the building valve 102 to the control panel 201 and from the control panel 201
to the
peripheral units 303 via the wireless communication system 104.
[00139] Once the water valve is closed as a result of a manual override input
being
received at one of the components of the system 100 (e.g. a peripheral unit
303), the
system 100 may not cause the water valve 102 to reopen (including, when motion
is
detected by one of the peripheral units 303) until input has been received at
one of the
components of the system 100 for causing the reopening of the water valve 120.
For
instance, a user may enter a passcode at the input interface 214 of the
control panel 201
for causing the reopening of the water valve 102, where a command is
transmitted to the
water valve 102 for actuating the reopening of the water valve 102. In other
examples,
the control panel 201 or a peripheral unit 303 may receive wirelessly input
from a user
using an external computing device for causing the reopening of the water
valve 102. The
user input sent via the external computing device, may be, e.g., the user's
credentials, a
password or a command associated with reopening the water valve 102. In other
37
Date Recue/Date Received 2020-07-10
examples, the user input for reopening the water valve 102 may be received at
the input
interface 314 of the peripheral unit 303.
[00140] Figure 6 outlines a method for controlling a flow of water into a
building based
on sensor input. The following description refers to Figures 1-4 and 6 to
describe the
method in detail and to demonstrate how a water regulation system, such as the
exemplary water regulation system 100, may be used to implement it.
[00141] In the method of Figure 6, either step 638 or steps 639a and 639b may
be
performed. In step 638, a peripheral unit 303 may detect the presence of a
human
operator. The detection may be performed by a motion detector 316 or 216 as
described
above. The detected presence may comprise a sensor input. In step 639a, a
peripheral
unit 303 or an attached probe 106 may measure moisture or another condition as
described above. The measurement may comprise a sensor input. In step 639b,
the
probe 106 may transmit the measurement to the peripheral unit 303 or the
control panel
201.
[00142] In step 640, the peripheral unit 303 or the control panel 201 may
receive the
sensor input.
[00143] When the input is received by the peripheral unit 303, steps 643-648
mirror
steps 543-548 outlined in Figure 5 and described above. The description
provided above
of the steps and potential variations and additions applies to steps 643-648.
Where a
user input is described above, the method handles a sensor input in the
present method.

[00144] In a first exemplary embodiment, the sensor input may comprise
detected
motion proximate a peripheral unit. In step 645, the main controller 211 may
produce a
command to allow a flow of water into the building so that the human operator
proximate
the peripheral unit may use the water. In a second exemplary embodiment, the
sensor
input may comprise detection of a high level of moisture by a probe 106 in an
area where
moisture is not desired, which will result in the closing of the valve. The
advantages
described above for responding to user input through presently described
methods also
apply to responding to sensor input through presently described methods.
[00145] Although the invention has been described with reference to preferred
